IMPROVEMENT IN METHODS OF UNITING THE RUBBER ROLLS 0F WRINGERS.

Specificationforming part of Letters Patent No. 209,781, dated November12, 1878; application filed March 6, 1878.

To all whom it may concern:

Be it known that I, HENRY N. STRONG, of Cornwall, in the county ofOrange and State of New York, have invented a certain novel and usefulImprovement in the Method of Ooverin g Spindles or Shaftin g forClothes- Wringers, 850., with India-RubberTubing; and I hereby declarethat I have herein set forth the manner in which the same is to beaccomplished.

Referring to the drawings, Figure 1 is a vertical sectional view of arubber tube or roll, T, in the state of being forced upon the conicalperforated sheath. S, which is filled with cement, in a liquid state,preparatory to receivin g the metallic shaft or spindle O, which isforced down into the sheath S in such a manner that a portion of thecement will escape out through the holes a n, so as to lubricate theouter surface of the conical tube or sheath, so that the same may bedrawn with greater ease through the tubing T, thus leaving the spindleor shaft 0, with its cemented coating, in position in the flexibletubing ready for use. A'is the supporting-bracket, with a projection, u,to support the india-rub ber tube or roll T. Said projection isperforated through the center thereof, so as to leave an opening largeenough to allow the sheath S to pass through the said hole or openingwhen drawn out by means of the rod m, operated by any suitable power, orotherwise. B B are metallic bands, employed to firmly hold the tube T ina suitable position against the face of the bracket or frame A, to whichthe said bands B are firmly secured, and they are of sufficient capacityto allow the tubing T to be inserted into and removed from the sameafter receiving the shafting G, as above set forth.

Fig. 2 is a representation of a flexible roller, T, mounted upon themetallic bearing or shafting 0, ready for use.

Fig. 3 is a vertical sectional drawing of the perforated conical sheathor tube S, to be made of any suitable material to receive the shaft 0into its cement-chamber, so that the said shaft becomes perfectly coatedwith the adhesive gum while the sheath is being drawn through the rubbertube until the upper end of the said tube or jacket T, Fig. 1, strikesagainst the projecting flange or rim 0 on the shaft, when the sheath Tis drawn out, ready for another tube, leaving the rubber roll on themetallic shafting O in the position shown at Fig. 2. v

I disclaim W. Oowless Patent No. 201,096, dated March 12, 1878.

The novelty of my invention consists in the method of securin g therubber jacket or flexible roller to the metallic shafting of aclotheswringer in the manner as above set forth.

What I claim as novel and useful, and wish to protect by Letters Patentof the United States, is-- The method, as described, of uniting therubber rolls of the wringers to their metallic shafts by forcing thesaid rolls upon a conical hollow perforated sheath, filling said sheathwith liquid cement, driving the metal shaft into the open end of thesheath, thereby causing the cement to exude from the perforations oropenings upon the rubber, and finally withdrawing the sheath, thusallowing the rubber to contract upon the shaft, substantially as and forthe purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

HENRY N. STRONG.
